Can a Terraform local value reference other local values?

In Terraform, local values are essentially named expressions that can hold a single value, which can be referenced later in your configuration. The ability for one local value to reference another is a key feature of Terraform's functionality, allowing for greater modularity and reusable code.

When you define a local value, you can use other local values in its expression. This is particularly useful for organizing complex configurations where certain values are derived from or dependent on previously defined values. For example, you might have a local value that computes a base URL and another that appends an endpoint to it, relying on the first local value to do so.

This approach not only simplifies the management of your configurations but also improves readability and maintainability by allowing interdependencies between local values. Consequently, stating that a local value can reference other local values is accurate, as it reflects Terraform's design aimed at promoting efficient and clear infrastructure as code practices.
